      Description

      When an application wants to use I&M5 to present OEM information not related to the communication module but to another module, (e.g. in case of re-brandlabeling) it has to enable I&M5 via Set OEM Parameter 5 services. Up to PNS V4.6.0.x this automatically made the protocol stack add an additional block to DCP Identify Response frames. This DCP OEM ID block always contained Hilscher VendorID and DeviceID, other values could not be used. This will be inconsistent to the I&M5 data for non-Hilscher devices.
      The Profinet specification does not mandate usage of the DCP OEM ID block even if I&M5 is enabled.

      Thus, the DCP OEM ID block shall no longer be added automatically.

      Usage DCP OEM ID block shall explicitly be enabled with new Set OEM Parametertype 21 containing the Vendor & Device ID.
